Performance Analysis of Industrial Boiler

Boiler performance analysis is necessary activity in industry to work out it efficiency. Energy efficiency of boiler is key parameter in performance test which indicate how efficiently energy conversion taking place. Inefficient energy conversion leads to waste of energy resource and pollution too. Energy resources are scare and depleting very fast day by day to cater need of large population. Fuel price is increasing day by day therefore its efficient use is prime concern for any industry [1]. The preset work is about performance analysis of industrial boiler which is carried out at Yash Chemicals Pvt Ltd, Bhavnagar. This analysis mainly focus various energy losses in wood fire boiler system. Various losses like heat loss due to flue gas, heat loss due to moisture in fuel, heat loss due to unburnt coal in bottom ash, heat loss due to incomplete combustion of fuel, heat loss due to radiation and convection and heat loss due to insulated and uninsulated surface were calculated by using standard equations [2]. Fuel consumption rate, steam pressure, temperature and flow rate, ambient air temperature, flue gas temperature etc., one month Data is taken for energy analysis. The major energy losses are heat loss due to flue gas (19%), and heat loss due to moisture in fuel (8.8%). It was suggested that to use heat recovery from exhaust flue gas by putting economizer. Fuel (wood) should be dried by a suitable dyer and it should be broken in small sizes between 25mm to 40 mm (according to Bureau of energy efficiency guide line). Proper Insulation and using VFD fan for boiler system could play major role in increase energy efficiency of boiler system.
